@Andree143 Your linked profile has no listing or guest reviews attached to it, so I can't tell how much experience you have as a host or what kind of listing you have. Some kinds of details do seem to attract a disproportionate share of people seeking to use the home for illicit activities - such newer hosts without security/monitoring features, and Entire Home rentals with exceptionally low rates for the area.
I agree with @Helen3 that vetting is important, and until you have a firm handle on that, I would strongly suggest leaving Instant Book off. You might also consider adjusting your Minimum Stay, if you're finding more problems with one-night guests.
And of course, the elephant in the room: in light of the pandemic, are the attractions and amenities that visitors in your area normally enjoy currently up and running? If not, all the more reason to question why someone might need short-term accommodation there.
